How the Five Compare on the Numbers
When one socket is spoken for and the machine on it is a microwave, the bowl you reheat in stops being a detail. Four of these five publish a microwave statement and they are not the same statement: two cover the set, one covers the set with the lid taken off, and one covers the lid and says nothing about the bowl. The fifth is stainless steel and offers a refrigerator and a freezer instead.
Underneath that, the published capacities run from 0.32 quarts to 5.8 quarts, in quarts on three listings and in both quarts and milliliters on a fourth. Two listings publish more bowls than sizes: one states six bowls and lists five sizes, the other states seven bowls and lists five. Three publish a weight and two publish none.
What the table cannot settle is what Pyrex’s glass is rated for, because the listing puts its freezer, microwave and top rack dishwasher claim on the plastic lid and makes no statement about the bowl. Cuisinart is the clearest case in the other direction: stainless steel, stated safe in a refrigerator and a freezer, with no microwave claim because steel does not belong in one.
Four Microwave Claims, Four Different Scopes
Two That Cover the Whole Set
Oggi publishes the plainest version: dishwasher, microwave and freezer safe BPA free hard plastic bowls, with clear airtight lids and a ribbed base for grip. It is a set of four at 0.7, 1.4, 2.6 and 4 quarts, in four color combinations, published at 1.81 lb with a carton of 9 by 9 by 5 inches. Four bowls, four sizes, and one claim that covers them.
BAKKENMASTER publishes the same three machines for polypropylene bowls with tight sealing TPR lids, adding that the set is safe at every stage of prep. It is where the bowl count stops matching: the listing states six plastic bowls with six lids and then publishes five sizes, at 0.32, 0.74, 1.37, 3.69 and 5.8 quarts. One of the six bowls has no published size.
One With the Lid Off, One Only the Lid
SCWBOEII states microwave safe and then qualifies it in the same breath, take off the lid, which is the only conditional microwave claim on this page. It publishes its capacities twice, in quarts and milliliters, from 0.71 quarts or 680 ml up to 5.17 quarts or 4900 ml, and states seven bowls against those five sizes.
Pyrex publishes the narrowest claim of the four and the listing is precise about it: the BPA free plastic lid is freezer, microwave and top rack dishwasher safe. The bowls themselves are described as sculpted tinted glass in 1.3, 2.3 and 4.5 quart sizes, and nothing in the five bullets states what the glass may be heated in. At 8.89 lb it is also the heaviest set here.
What the Counts and the Cartons Say
More Bowls Than Sizes
Two of these five publish a bowl count their size list does not support. BAKKENMASTER states a 12 piece set of six bowls and six lids and lists five capacities. SCWBOEII states seven bowls with airtight lids and lists five, adding that the detailed sizes are shown in the picture, which is not a specification. In both cases a buyer counting on a specific bowl is counting on an image.
The other three are consistent. Oggi publishes four sizes for four bowls, Pyrex three for three and Cuisinart three for three, at 1.5, 3 and 5 quarts. Across all five listings the published range runs from 0.32 quarts to 5.8 quarts, and only SCWBOEII lets those figures be checked in a second unit, at 680 to 4900 ml.
One Carton That Cannot Be Right
BAKKENMASTER’s published package figure is 3 by 3 by 5 inches, for a set that contains six nesting bowls and six lids, the largest of them holding 5.8 quarts. That cannot describe the carton, and this page does not use it for anything. The other three carton figures are plausible for what they hold: 9 by 9 by 5 inches for four bowls, 10.5 inches cubed for three steel bowls, and 11 by 11 by 12 inches for three glass ones.
None of the five publishes the size of the nested stack itself, which is the figure that decides the cupboard. Elsewhere in this pool exactly one listing does, giving 7.75 by 9.5 by 6.5 inches for its nested set, and it is a rectangular container range rather than a bowl set. On these five, the carton is the closest thing available and one of the four is wrong.
The Steel Set and What It Trades
A Refrigerator and a Freezer Instead
Cuisinart publishes three stainless steel bowls at 1.5, 3 and 5 quarts, stated dishwasher safe and stated safe for the refrigerator and the freezer so prepped ingredients or chilled dough can be stored in the bowl. It publishes 3.9 lb and a 10.5 inch cubed carton, and it publishes no lids at all, which is the other half of what a storage bowl usually offers.
No microwave claim appears, and none should. What that costs in a kitchen with one socket is the reheating step: the food comes out of the bowl and onto a plate before it goes in the machine. What it buys is a bowl that will not stain, will not hold flavors and takes a whisk or a hand mixer without flexing.
Where Glass Sits Between the Two
Pyrex is the interesting middle case. Glass is the material most people would reheat in without thinking, and this is the listing that publishes a microwave claim for its lid and not for its bowl. It publishes 1.3, 2.3 and 4.5 quart sizes, a stated perfect lid fit, and manufacture in the USA, and it weighs 8.89 lb for three bowls.
For a kitchen choosing on this axis, the honest reading is that the plastic sets are the ones whose bowls carry the claim. The glass set says its lid is safe, the steel set does not raise the question, and two of the plastic sets cover everything. The third plastic set covers the bowl on the condition that its lid comes off first.
Which One Fits Your Kitchen
Reheating without thinking about it. Oggi, four BPA free hard plastic bowls at 0.7, 1.4, 2.6 and 4 quarts with clear airtight lids and a ribbed base for grip, stated dishwasher, microwave and freezer safe, published at 1.81 lb in a 9 by 9 by 5 inch carton.
The widest published range. BAKKENMASTER, six polypropylene bowls with six tight sealing TPR lids, published at 0.32, 0.74, 1.37, 3.69 and 5.8 quarts, stated dishwasher, microwave and freezer safe, with one bowl whose size is never given and a carton figure that cannot be right.
Capacities you can check twice. SCWBOEII, seven plastic bowls with airtight lids published in both units, 0.71 quarts or 680 ml up to 5.17 quarts or 4900 ml, stated microwave safe with the lid taken off, stackable and nesting, with no weight published.
Glass on the table. Pyrex, three sculpted tinted glass bowls at 1.3, 2.3 and 4.5 quarts with BPA free plastic lids stated freezer, microwave and top rack dishwasher safe, made in the USA, published at 8.89 lb in an 11 by 11 by 12 inch carton.
Mixing, then chilling. Cuisinart, three stainless steel nesting bowls at 1.5, 3 and 5 quarts, stated dishwasher safe and stated safe in the refrigerator and the freezer, published at 3.9 lb in a 10.5 inch cubed carton, with no lids and no microwave claim.
What We Could Not Verify
Every figure above is quoted from the listing that published it. These are the things a kitchen reheating in one machine would want and no listing here answers.
- Pyrex publishes its microwave claim for the lid and states nothing about the glass bowl.
- BAKKENMASTER states six bowls and publishes five sizes.
- SCWBOEII states seven bowls and publishes five sizes, with the rest left to a photograph.
- BAKKENMASTER’s published carton, 3 by 3 by 5 inches, cannot hold six bowls up to 5.8 quarts.
- None of the five publishes the size of the nested stack.
- No listing states a temperature or a time for the microwave use it claims.
